More Info on Interactions With Irbesartan/HCTZ
Taking irbesartan/HCTZ with pentoxifylline may lower your blood pressure to unsafe levels. Your healthcare provider may choose to monitor your blood pressure more closely if you take these medications together.
If you take potassium products with irbesartan/HCTZ, your blood potassium levels may become too high. Check with your healthcare provider before taking any potassium product with irbesartan/HCTZ.
Combining irbesartan/HCTZ with potassium-sparing diuretics could increase your risk for high blood potassium (hyperkalemia). It could also cause your blood pressure to become too low. Talk to your healthcare provider about this potential interaction before taking these medications together.
Pressors are normally used to increase blood pressure in cases of very low blood pressure. Irbesartan/HCTZ may affect the ability of pressor medications to raise blood pressure.
Taking irbesartan/HCTZ within 12 hours of rituximab could lower your blood pressure to unsafe levels. Talk to your healthcare provider about this possible interaction if you are receiving rituximab treatment.
Combining irbesartan/HCTZ with tolvaptan could increase your risk for high blood potassium (hyperkalemia). Your healthcare provider may choose to monitor your blood potassium levels if you take these medications together.
Hydrochlorothiazide (HCTZ) can increase the level of topiramate in the blood, increasing the risk for topiramate side effects, such as low blood potassium. Because irbesartan/HCTZ contains HCTZ, your healthcare provider may need to decrease your topiramate dosage and monitor your blood potassium levels if you take these medications together.
